DIE FOR SAW-SWAG-ES.

Specification of Letters Patent. Patented Mar, 31, 1914 Application filed May 26, 1913. Serial No. 769,910.

To all whom it may concern:

Be it known that I, ARTHUR K. HANCHETT, a citizen of the United States, residing at Big Rapids, in the county of Mecosta and State of Michigan, have invented certain new and useful Improvements in Dies tor Saw-Swages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to saw swages and relates more particularly to an improved construction of the rotating die of the swage whereby the removal and replacement of the die are facilitated.

The type of swage in connection with which my present improvement is especially adapted to be employed is illustrated in the accompanying drawings, in which- Figure l is a side view of the swage applied to a saw blade, Fig. 2 is a part sectional view of the same; Fig. 3 is a perspective detail of the die and the latch plate by which the die is held in the swage block; Fig. 4 is a perspective view of a die and its anvil, broken away in part.

As is clearly shown in the drawings, the device consists in the usual swage block 1 having a saw receiving recess 2, an anvil 3 and an eccentric cylindrical die 4 revolubly mounted in the swage block and adapted to be turned by means of the operating handle 5.

In my improved construction I employ the usual eccentric die with annular groove 6 near one end to receive the locking plate 7, which is removably fixed to the swage block 1 by a screw 8.

By the former construction it has been possible to remove the die from the swage, but only by first loosening the anvil from the block and then raising the anvil up so as to permit the die to be slid out endwise. This procedure had the disadvantage in practice that a die when it became worn and required to be removed and a new one inserted necessitated the raising of the anvil, which put the anvil out of adjustment. After the new die was inserted the anvil had to be lowered to the proper point, making it necessary to readjust the swage each time a new die was put in. construction I form a V-shaped groove 9 eX- tending lengthwise from the eccentric lto the end of the die rod. This groove is of the same shape as the end of the anvil, and the bottom of the groove is flush with the periphery of the die l. When the die is turned to the position shown in Fig. L the groove is in register with the end of the anvil, as indicated in Fig. 4. The locking plate 7 may then be raised permitting the die to slide out endwise without disturbing the adjustment of anvil 8. A new die may then be inserted and locked in place by plate 7 Having described my improvement what I claim and desire to secure by Letters Patent is 1. In a swage of the class described, an eccentric cylindrical die having one end formed with a longitudinal groove adapted to receive the end of the anvil of said swage, for the purpose set forth.-

2. In combination with a swage, a die, said die formed with a longitudinal groove adapted to receive the anvil of said swage to permit the removal of the die, and a looking plate secured to the body of the swage and removably engaging said die.

In testimony whereof, I aflix my signature in presence of two witnesses.
